I have chrysographes Iris in the wet bit beside my pond. They don't flower for long, but they're beautiful while they do
I also have the white version of Marsh Marigold (Caltha) near them. The yellow one is ideal for wet spots, but it can take over a bit if you're not careful!
Ferns are ideal, and there's one for every type of site - wet or dry, sunny or shady.
I have a Phormium and a Libertia in the drier bit. They provide evergreen cover for wildlife.
As B'cupdays says, if you give us a little more info about the type of pond, sizes, aspect and soil, you'll get lots more suggestions.
